The utility model content
The purpose of this utility model provide a kind of simple to operate, with the abrading-ball operating mode is more approaching, test figure is relatively accurate, experimental enviroment good, efficient is high drop type abrading-ball testing machine.
The technical solution of the utility model is: an internal diameter is fallen the top that percussion device is fixed on supporting seat greater than the tubulose of abrading-ball approximately, this of device upper end connection is received and is fallen conduit, this device lower end is fixedly connected with the abrading-ball orbit, the dead ahead of orbit is equipped with a chapelet that is driven by reducing motor, the bucket of chapelet bottom and the left end of orbit just in time join, at this interface a timing automatic flexible baffle means is arranged, automatically telescopic baffle is to drive cylindrical gear by three-phase hybrid stepping motor to drive the bar gear again and realize having only a ball to enter in the bucket of chapelet along orbit with assurance by limit switch when clashing into.Abrading-ball by chapelet rise to be thrown into behind the certain altitude receive and the conduit that falls in and fall abrading-ball distribution bump in the percussion device with abrading-ball, reach the purpose of Automatic Cycle bump.Their controller of timing counter, milling ball breaking alarm device and control of drop number when above orbit, being provided with broken time of record abrading-ball circulation drop number and abrading-ball and fragmentation.
Described milling ball breaking alarm device is commercially available JSL-33x milling ball breaking alarm device.
Controller control milling ball breaking alarm device is that the image information of the detected abrading-ball of CCD solid state image sensor will be sent into microprocessor by modulus/digital-to-analog conversion (A/D) after the information processing, whether damaged by the microprocessor judges abrading-ball, if it is damaged, then pass through JSL-33X: audible-visual annunciator is reported to the police, and cut off the hoister power supply immediately, hoister is quit work.，
Described electronic timer and counter is a commercially available EP105 timing counter.
Controller is sent into microprocessor with the detected information of EP105 timing counter after by information processing, and shows on display CRT.
The utility model can be adjusted the hoisting depth of chapelet and the falling height of test ball as required, machine works is steady, simple to operate, with the abrading-ball operating mode more approaching, test figure is relatively accurate, experimental enviroment good, efficient is high, is applicable to scientific research institutions, the institution of higher education of abrading-ball manufacturing enterprise and abrading-ball performance study.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment:
In conjunction with the accompanying drawings:
Present embodiment is that a supporting seat 1 is installed on the ground, the tubulose that is Φ 65 by an internal diameter falls the top that percussion device 2 is fixed on supporting seat 1, the upper end that abrading-ball falls percussion device 2 is that the receiving of Φ 65 and the conduit 3 that falls connect by web member and internal diameter, whereabouts conduit 3 is provided with a side door 12 of putting ball, install 2 ends and connecting firmly the abrading-ball orbit 10 that internal diameter is Φ 65, a chapelet 4 that is driven by reducing motor 5 has been installed in the dead ahead of abrading-ball orbit 10, on the present embodiment chapelet, lower shaft centre distance is 6500mm, the bucket 17 of chapelet bottom just in time joins with the left end of orbit, at this interface a timing automatic telescopic baffle 9 is arranged, automatically telescopic baffle 9 is to drive cylindrical gears 14 by three-phase hybrid stepping motor 13 to drive bar gear 15 again and realize by limit switch 16.Guarantee only to have a ball when bump, to enter in the bucket of chapelet along abrading-ball orbit 10 smoothly, abrading-ball 18 by chapelet drive be thrown into behind the certain altitude receive and the conduit 3 that falls in, and fall abrading-ball distribution bump in the percussion device 2 with abrading-ball that the lower end connects firmly, reach the purpose of Automatic Cycle bump.
A commercially available EP105 timing counter 6 and commercially available JSL-33x cracker warning device 8 are installed above abrading-ball orbit 10 and are controlled their controller 7.
In conjunction with Fig. 4:
Controller 7 is that the image information of the detected abrading-ball of CCD solid state image sensor is sent into microprocessor by modulus/digital-to-analog conversion A/D after with information processing, whether damaged by the microprocessor judges abrading-ball, if it is damaged, then report to the police by the JSL-33X audible-visual annunciator, and cut off the hoister power supply immediately, hoister is quit work.
